Iren S A -ES iMPnovE-MENT lhl MACHINES-FOR MAKING :R'oP Li fSpecification forming part of Letters Patent No. l9,099, dated April 3,-1877 application filed g Ju1y7,-1'876 f Belleville,' Essex county, NewJersey, have ,in-

vented an Improvement in Machines for Making vWire and other Rope; and 1do hereby declare the following to be a fulland correct description ofthe same,r-:ference being had to the accompanying drawings, in whichFigure. 1. is. asidevelevation with a part broken away, showing asection of the drum. Fig. 2 is a part of one of, the reels,=andFig. 3 asection through the drum upon the-line w y, Fig. 1.

The object of my invention is to' make a machine for making ropecomplete by one operand then were twisted together by a separate anddistinct operation. But my machine forms the initials and twists themtogether, finishing the rope at one operation.

Myinvention consists of a series of revolving frames, each of whichforms an initial, and said initials pass through a guide upon leavingthe revolving frames and are twisted into a rope and wound upon a drum,combining a mechanism for forming the initial strands with mechanism fortwisting said strands into a finished rope.

In the drawings, A represents the main driving-shaft, upon which are thepulleys a b for driving the revolving heads, and the pulley c fordriving the finishing mechanism and drum. B B is a frame which supportsthe bearings of the revolving heads D D D, and the frame 0 0 supportsthe bearings of the twisting mechanism E and drum F. The frame B maysupport any number of revolving heads, each of which is constructedsimilar to the other. G is a frame revolving upon hollow bearings I inthe frame B B. Within the frame G is a smaller frame, H, revolving uponan independent axis within the hollow bearing I, the outer endterminating in a plate,

J, guided by the cross-piece K in the frame G. The frame or plate Hcarries three or more spools, L, which revolve idly upon their own axis.The frame G revolves at a much lower speed than the frame H carrying thespools L. The speed of the frames G and H is regulated by the size ofthe pulleys M and N and a and b. The axis of the spools L is Heretoforethe initials were first madef j hollow, withran orifice in one side,meatwhich an arm,extendi ng outward from said hollow axle, carries apulley, over which the wire or thread from the spool is conveyed intoand through the hollow axle. In the-plate J, which revolves in thecross-piece'K, are holes,

through which the wire or thread from the spoolspass and unite in thehollow journalL' Supportedin the frameO O is the twisting and finishingmechanism which consistsof the hollow shaft 0 driven by the pulley Atthe entrance of this hollow shaft are two grooved pulleys, g' and h,which revolve with the shaft 0, and receive the rope first around onethen around the other, and twist the rope in a uniform manner. Similargrooved pulleys s s are placed upon the ends of the hollow shafts I, ifdesired. Upon the opposite end of the hollow shaft 0 is the feed ortake.

up drum F and rim P. The rim P revolves with the pulleyE, but the drum Frevolves faster, which motion is accomplished as fol lows: Upon thehollow shaft 0 is a stationary pinion, Q, which engages the cog-wheel R,and communicates motion to the pinion S, which engages in the rack T,Fig. 3, and carries the drum F. Between the frame B, bearing therevolving heads D and the finishing mechanism, is the guide U, havingthe arm V with a hole for the reception of each initial strand, and anarm, W, for the reception of the twisting-rope. The guide U is supportedupon a cross-rod, X, and may be adjusted and held in position by theset-screw Y.

The operation of my invention is as follows: The spools L having beensupplied with wire, with their ends directed over the small pulleys, andinto and through the hollow axis and through the orifices in the plateJ, out through the hollow shaft I, and around the pulleys s s, motionmay be communicated to the shaft A. The several wires from the severalspools L all uniting in the hollow journal I, and the heads D revolving,they must, of course, be twisted together into an initial strand, and aseach revolving head in each frame G is constructed to operate in asimilar manner, it is clear any number of initial strands may be made atthe same time. All these initials are united in the guide U by means ofthe arms V and W to form the finished rope,

FFICE which is carried on between the groove-pub ley, Z, and is woundupon the drum F. Thedrum F being geared to revolve faster than the ropeis twisted, it feeds the rope'along through its various processes ofuniting and twisting until the finished rope is at last wound completedupon the drum. l

It will be observed that, when it is desirable to make but a single cordor initial, the

irames around the spools may be geared to -revolve in an oppositedirection and at a high. rate of speed, and so augment the twist of thecord at a rate equal to the sum of the velocities of the tworevolutions, whichis a very desirable result in rope making; or, ifdesired,

the said frames may be revolved in the same direction with plates H, thespeed of the latter being proportionally increased, the result of whichwouldbe to tighten thetwist of the strand after it leaves the rollers s8.

Having thus fully described my invention, What I claim, and desire tosecure by Letters Patent, is-- 1. The combination of the spools L,revolv- 1 ing upon hollow spindles upon the revolving plate H, withguide J, and hollow spindle I,"-

having pulleys 8 s, and arranged to. revolve substantially as described.

2-. l he stationary guides V and W, in combination with hollow shaft O,-having the grooved pulleys h and g, and with revolving plate P, andtake-up or feed-drum F, arranged together substantially as described.

3.--The drum F, provided with the rack T, in combination with therevolving plate P, gearw'heels Q and R, and pinion S, substantially asdescribed. l y

4. The combination of the revolving heads D, carrying spool L, auxiliarytwisting hollow spindle I, and guide J, with stationary guides V W, anda twisting device consisting of groovedpulleys g and h, hollow shaft 0,plate P, and take-up drum F, substantially as de scribed. l M r Theabove specification of my said invention signed andwitnessed at Newark,New Jersey, this l lth day of May, A- D. 187 6.
